CD54 [ICAM-1] (mouse):Fc (mouse) (rec.) (non-lytic)

The extracellular domain of mouse CD54 [ICAM-1] (aa 28-485) is fused at the C-terminus to the Fc portion of a mutant mouse IgG2a. Lyophilized from 0.2µm-filtered solution in PBS. Shows the biological function of the CD54 moiety and exerts a prolonged circulating half-life caused by the modified Fc domain. Intercellular Adhesion Molecule-1 (ICAM-1, CD54) binds the leukocyte integrins LFA-1 and Mac1. CD54 expression is weak on leukocytes, epithelial and resting endothelial cells, as well as some other cell types, but expression can be stimulated by IFN-gamma, TNF-alpha, IL-1beta and LPS. Soluble CD54 is found in a biologically active form in serum, probably as a result of proteolytic cleavage from the cell surface, and is elevated in patients with various inflammatory syndromes such as septic shock, LAD, cancer and transplantation.
